C/C++ Programming with Qt 5.12.6 and Opencv 4.2.0
C/C++ programming with Qt 5.12.6 and OpenCV 4.2.0 Preparation of the computer • Download http://download.qt.io/archive/qt/5.12/5.12.6/qt-opensource-windows- x86-5.12.6.exe and http://www.ensta-bretagne.fr/lebars/Share/OpenCV4.2.0.zip (contains OpenCV with extra modules built for Visual Studio 2015, 2017, 2019, MinGW Qt 5.12.6 x86, MinGW 8 x64), run Qt installer and select Qt\Qt 5.12.6\MinGW 7.3.0 32 bit and Qt\Tools\MinGW 7.3.0 32 bit options and extract OpenCV4.2.0.zip in C:\ (check that the extraction did not create an additional parent folder (we need to get only C:\OpenCV4.2.0\ instead of C:\OpenCV4.2.0\OpenCV4.2.0\), right-click and choose Run as administrator if needed). For Linux or macOS, additional/different steps might be necessary depending on the specific versions (and the provided .pro might need to be tweaked), see https://www.ensta-bretagne.fr/lebars/Share/setup_opencv_Ubuntu.pdf ; corresponding OpenCV sources : https://github.com/opencv/opencv/archive/4.2.0.zip and https://github.com/opencv/opencv_contrib/archive/4.2.0.zip ; Qt Linux 64 bit : https://download.qt.io/archive/qt/5.12/5.12.6/qt-opensource-linux-x64-5.12.6.run (for Ubuntu you can try sudo apt install qtcreator qt5-default build-essential but the version will probably not be the same); Qt macOS : https://download.qt.io/archive/qt/5.12/5.12.6/qt-opensource-mac-x64-5.12.6.dmg . -

KDE Published : 2017-06-26 License : GPLv2+ 1 KDE DU POINT DE VUE D'UN DÉVELOPPEUR 1. AVEZ-VOUS BESOIN DE CE LIVRE ? 2. LA PHILOSOPHIE DE KDE 3. COMMENT OBTENIR DE L'AIDE 2 1. AVEZ-VOUS BESOIN DE CE LIVRE ? Vous devriez lire ce livre si vous voulez développer pour KDE. Nous utilisons le terme développement très largement pour couvrir tout ce qui peut conduire à un changement dans le code source, ce qui inclut : Soumettre une correction de bogue Écrire une nouvelle application optimisée par la technologie KDE Contribuer à un projet existant Ajouter de la fonctionnalité aux bibliothèques de développement de KDE Dans ce livre, nous vous livrerons les bases dont vous avez besoin pour être un développeur productif. Nous décrirons les outils que vous devrez installer, montrer comment lire la documentation (et écrire la vôtre propre, une fois que vous aurez créé la nouvelle fonctionnalité !) et comment obtenir de l'aide par d'autres moyens. Nous vous présenterons la communauté KDE, qui est essentielle pour comprendre KDE parce que nous sommes un projet « open source », libre (gratuit). Les utilisateurs finaux du logiciel n'ont PAS besoin de ce livre ! Cependant, ils pourraient le trouver intéressant pour les aider à comprendre comment les logiciels complexes et riches en fonctionnalités qu'ils utilisent ont vu le jour. 3 2. LA PHILOSOPHIE DE KDE Le succès de KDE repose sur une vue globale, que nous avons trouvée à la fois pratique et motivante. Les éléments de cette philosophie de développement comprennent : L'utilisation des outils disponibles plutôt que de ré-inventer ceux existants : beaucoup des bases dont vous avez besoin pour travailler font déjà partie de KDE, comme les bibliothèques principales ou les « Kparts », et sont tout à fait au point. -
